Hydroxyurea to Prevent Stroke in Children With Sickle Cell Anemia and Elevated TCD Flow Velocity

Completed

Summary of Purpose

The purpose of this study is to assess prospectively the efficacy of hydroxyurea therapy in the setting of cerebrovascular disease, manifest as conditional or abnormal transcranial doppler ultrasonography (TCD) flow velocities, in children with sickle cell anemia (SCA). TCD is used to measure flow velocity in intracranial arteries as a marker of increased stroke risk in children with SCA. The primary objective...
